TELEPHONE INSTRUMENT.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed July 12, 1907. S'erial No. 383,493.

T b all whom it may concern:

Be it known that I, l\I1NoR WATERS, a citizen of the United States, residing at New Albany, in the county of Floyd and State of Indiana, have invented a new and useful Telephone Instrument, of which the following is a specification.

The present invention relates to telephone instruments, and the primary object is to provide novel means of a simple nature, which can be readily applied to an ordinary transmittmg and receiving set, said means constituting an effective support for the receiver that will hold the same in proper re-- lation to the ear of a user of the instrument, and also constitute actuating means for the usual switch mechanism, the arrangement moreover being such that the actuating means constitutes a stop for limiting the movement of the receiver support.

In the accompanying drawings: Figure 1 is a perspective view of a desk telephone set, showing the improvement applied thereto. Fig. 2 is a detail sectional view through the switch actuating mechanism. Fig. 3 is a front elevation of a modified form of construction. Fig. 4 is a side elevation thereof.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment disclosed in Figs. 1 and 2, the desk set consists of a base 5 carrying a standard 6 that supports the usual transmitdamping ter 7. In the standard is located the usual switch mechanism controlled by an outstandin swinging arm 8. The arm has its outer en d enlarged as shown at 9, and provided with a vertical opening or slot 10. A stem 11 has at one end a foot 12 secured to the standard 6 by screws 13, and a swinging arm comprising sections 12 and 13", has the section 12 pivotally mounted, as shown at 14 on the outer end-of the stem 11. tions are pivotally connected by a bolt 15, and a clamping nut 16, threaded on the bolt,

serves to hold the sections against relative and in different positions. A oke orband 17, fastened to the has and o the section 13 by a bolt 18, is arganged to embrace and securely hold the 19 upon the free end of the "A cam finger 20, secured. to the arm 2"*-'1-13', passes through the slot 10 of the switch arm, and has its secured end disposed movement to the axis of movement of the arm .12'-.-13 than the free end of said cam finger.

The sec- Said free end terminates in a depending hook 21 that constitutes a stop, engaging the switch arm 8 to limit the swinging movement of the receiver supporting arm.

The cam linger 20 is so disposed with relation to the lower end of the slot 10 in the switch arm that when the receiver supporting arm is in upright position, said finger will hold the arm 8 in depressed position, but when the arm 12--13" is swung forwardly, the arm 8 is permitted to rise.

The forward movement of the arm 12 13 is limited as already explained by the stop hook 21, and when in its forward position, the receiver 19 is in proper relation to the ear of the user of the instrument. It will be observed that by adjusting the sections 12 -13, this forward position can be varied as desired. Thus it will be seen that a simple and effective support for the receiver is provided which can be readily attached to the ordinary instrument and effects the operation of the switch mechanism. The passing of the cam finger 20 through the opening is important, inasmuch as the walls of said opening prevent the lateral displacement of the finger 20, and thus at all times insures its proper cooperation with the switch arm.

That the mechanism is readily applicable to a wall instrument will be evident by reference to Figs. 3 and 4. In said figures, the switch actuating arm is designated 22, and has the vertical slot 23 in its outer end. A stem 24, secured to the side of the casing of the instrument, has the sectional arm 25 pivoted thereon. The outer end of this arm carries a receiver clamping band 26, and an actuating finger 27, secured to the arm, passes through the slot 23, andterminates in a stop hook 28, which limits the swinging movement of the arm, and consequently the forward movement of the receiver. It will be evident that this mechanism operates in the same manner as the first described embodiment, and has all the advantages thereof.

From the foregoing, it is thought that the construction, operation and many advan tages of the herein described invention will be apparent to those skilled in the art without iurther description, and it will be understood that various changes in the size, shape, proportion and minor details of constructlon may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention,

i 1. In mechanism of the character set forth, 7

' the combination with a telephone instrument having a switch, of a receiver support movable toward and from the switch, and switch actuating means operated by the support and engaging the switch, a portion of said means constituting a stop that engages the switch to limit themovement of the support away from the switch.

2. In mechanism of the character set forth, the combination with a telephone instrument having a switch, of a swinging receiver supporting arm having a movement toward and from the telephone instrument, and switch actuating means carried by the arm and engaging the switch; a portion of said means constituting a stop that engages the switch to liniit the swinging movement of the arm away from the telephoneinstrument.

3. In mechanism of the character set forth, the combination with a, telephone instrument having an outstandingswitch arm that is provided with an opening, of a swinging receiver supporting arm, and a cam finger carried by the supporting arm and slidably.

passing throughand at all times remaining in the opening in the switch arm, the free end of the finger being disposed further from the axis of movement of the supporting arm than the end said arm being held against the combination with a telephone instrui ment having an outstanding switch arm, of a swinging receiver supporting arm, and a cam finger carried by the supporting arm and enaging the switch arm to move the same,,said

i er having a terminal stop hook that engages the switch arm to limit the swinging rnoyement of the sup orting arm.

' 5'. In mechanism 0 the characterset forth, the combination with atelephone instrument having an outstanding switch arm pro vided with an opening in its outer end, of a stem secured to the instrument, aswinging arm comprising pivotally connected sections, one of which is pivotally mounted on; the stem, a receiver holdingclamp. carried by the other section, a cam finger secured to the arm and passing through the opening in the switch arm, and a terminal stop hook carried by'the finger and engaging the switcharmto limit the swinging movement of the first mentioned arim I In testimony, that. I claim the foregoinga's my own I have hereto affixed my signature in the presence of two witnesses.
